Overview
CMOS LSI No.
5483 LC662304A, 662306A, 662308A, 662312A, 662316A Four-Bit Single-Chip Microcontrollers with 4, 6, 8, 12, and 16 KB of On-Chip ROM Preliminary Overview The LC662304A, LC662306A, LC662308A, LC662312A, and LC662316A are 4-bit CMOS microcontrollers that integrate on a single chip all the functions required in a special-purpose telephone controller, including ROM, RAM, I/O ports, a serial interface, a DTMF generator, timers, and interrupt functions.
These microcontrollers are available in a 42-pin package.
Package Dimensions unit: mm 3025B-DIP42S [LC662304A/662306A/662308A/662312A/662316A] 42 22 15.
24 Features and Functions • On-chip ROM capacities of 4, 6, 8, 12, and 16 kilobytes, and an on-chip RAM capacity of 512 × 4 bits.
• Fully supports the LC66000 Series common instruction set (128 instructions).
• I/O ports: 36 pins • DTMF generator This microcontroller incorporates a circuit that can generate two sine wave outputs, DTMF output, or a melody output for software applications.
• 8-bit serial interface: one circuit • Instruction cycle time: 0.
95 to 10 µs (at 3.
0 to 5.
5 V) • Powerful timer functions and prescalers — Time limit timer, event counter, pulse width measurement, and square wave output using a 12-bit timer.
— Time limit timer, event counter, PWM output, and square wave output using an 8-bit timer.
— Time base function using a 12-bit prescaler.
• Powerful interrupt system with 10 interrupt factors and 7 interrupt vector locations.
— External interrupts: 3 factors/3 vector locations — Internal interrupts: 4 factors/4 vector locations (Waveform output internal interrupts: 3 factors and 1 vector; shared with external expansion interrupts) • Flexible I/O functions Selectable options include 20-mA drive outputs, inverter circuits, pull-up and open drain circuits.
• Optional runaway detection function (watchdog timer) • 8-bit I/O functions • Power saving functions using halt and hold modes.
• Packages: DIP42S, QIP48E (QFP48E) • Evaluation LSIs: ...
